Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tire pressure modes are set to meet different vehicle conditions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system dynamically switches between multiple tire pressure modes (economic mode, sport mode, snow mode, etc.) based on real-time vehicle conditions including speed, acceleration, steering angle, and environmental factors. This dynamic adaptation allows the system to optimize tire pressure for different driving scenarios without requiring manual intervention, resolving the contradiction by making the system adaptable while managing complexity through automated condition-based selection.
Solution Approach 2:
The system changes the tire pressure parameter based on detected vehicle conditions and selected mode. By adjusting the reference tire pressure value according to different modes (e.g., lower pressure for economic mode, higher for sport mode), the system achieves versatility in meeting different performance requirements while using a single regulation mechanism, thus improving adaptability without proportionally increasing device complexity.
2Productivity
If reference tire pressure is adjusted based on vehicle speed, then tire performance is improved, but control complexity increases
Solution Approach 1:
The system pre-establishes multiple tire pressure modes with predetermined reference pressure values optimized for different vehicle speeds and driving conditions. Instead of calculating optimal pressure in real-time, the system selects from pre-configured modes based on current conditions, which simplifies the control logic while maintaining improved tire performance across different speed ranges.
Solution Approach 2:
The system continuously monitors vehicle speed, acceleration, and steering angle to determine the appropriate tire pressure mode. This feedback mechanism allows the system to automatically adjust reference tire pressure based on actual driving conditions, improving tire performance while keeping control complexity manageable through automated decision-making based on sensor inputs.
3Reliability
If tire pressure is regulated to prevent tire bursts, then safety is improved, but energy consumption increases
Solution Approach 1:
The system applies tire pressure regulation selectively based on detected risk conditions rather than continuously maintaining maximum safe pressure. When vehicle conditions indicate low risk (normal speed, stable driving), the system uses standard pressure values. When risk factors are detected (high speed, aggressive maneuvers), the system activates protection mode with adjusted reference pressure. This partial application of pressure regulation maintains safety when needed while reducing energy consumption during normal operation.

AI summary
The application discloses a method and device for regulating a tire pressure (P) of a vehicle and a storage medium. The method comprises: setting tire pressure modes each defining a reference tire pressure (S); acquiring information comprising a value of a vehicle speed (V) and a value of the tire pressure (P), a weather condition, a route, a predicted road condition and an energy state of the vehicle; selecting one tire pressure mode; determining a value of the reference tire pressure (S); and determining a difference for regulating the tire pressure (P). In some of the tire pressure modes, the reference tire pressure (S) is defined as a function of the vehicle speed (V) and has a lower value when the vehicle speed (V) increases within a specified range and a higher value when the vehicle speed (V) decreases within the specified range.
